KBOS Runway 15R/33L — Boston Logan International Airport
10,083 × 150 ft asphalt · true headings 135° / 315° · field elevation 20 ft
Runway 15R/33L at Boston Logan International Airport (KBOS) in Boston, MA is 10,083 ft long and 150 ft wide, asphalt, with true headings 135° and 315°. Over 2005–2025 the wind gave runway 15R the headwind 42.5% of the time and runway 33L 57.5%, with a crosswind above 15 kt in 4.2% of wind hours. KBOS publishes a digital ATIS, so this page shows the runway the tower is actually using right now and builds a record of how often each end is assigned.

ATIS Alerts Predicted Runway is an estimate from the TAF wind forecast and runway geometry (most headwind, crosswind penalised, tailwind over 5 kt avoided, longest runway breaks ties). It is not an ATC assignment and does not know about noise abatement, traffic flow or construction unless the D-ATIS states them. TAF issued 1720Z (1:20 PM EDT).

Runway 15R/33L numbers are magnetic; the stored geometry and every wind calculation on this page are TRUE north, so they never need a variation correction. Magnetic variation here is about 14.0°W (World Magnetic Model). Displaced thresholds, declared distances (TORA/TODA/ASDA/LDA), approach lighting, PAPI/VASI, ILS equipment and traffic-pattern direction are FAA NASR fields not yet loaded — they are omitted rather than guessed.
Recorded runway use at KBOS — last 30 days
How often the D-ATIS named each end for arrivals and departures (the facility's own statement).
ATIS Alerts records every change of KBOS's D-ATIS and turns it into a log of which runways the facility named for arrivals and departures. Recording started Sep 18, 2026 — 4 hours captured so far. Usage statistics appear once 24 hours are on record, and become meaningful after a few weeks.
Historical wind and crosswind on runway 15R/33L

From 175,153 hourly observations at KBOS (2005–2025), 167,701 with a steady wind direction (4.3% calm, variable or direction-less). One observation per clock hour; TRUE headings against TRUE wind.

“Wind-favored” counts the hours this end had the most headwind of every open runway at KBOS — wind arithmetic, not an ATC assignment (parallel runways with the same heading share the credit equally). Recorded D-ATIS use, where available, is the section above.

Runway 15R/33L closure history
Runway NOTAM history begins when the NOTAM feed goes live (next phase).
D-ATIS broadcasts recorded since Sep 18, 2026 declared runway 15R closed on 0 days and runway 33L closed on 0 days in the last 30 days. Scheduled and unscheduled closure NOTAMs, with start and end times and the official text, will appear here once ATIS Alerts records runway NOTAMs; there is no retrievable archive, so history accrues from that date forward.

Methodology and sources
- Active runwaysare read from the airport's D-ATIS text (community relay of the FAA broadcast) with an open, tested parser; the broadcast text is always shown. Every change is recorded, so “recorded use” is what the facility stated, never an inference.
- Wind components use the current METAR (aviationweather.gov) against TRUE runway headings from the OurAirports/FAA runway record.
- Predicted runway scores each open end from the TAF wind (headwind, crosswind penalty, tailwind avoidance, longest-runway tie-break); confidence falls with forecast distance, gusts and TAF age. It does not model noise abatement or flow programs.
- Climatology: Iowa Environmental Mesonet ASOS archive, one observation per hour, 45° wind sectors, percentiles via t-digest; runway geometry is today's record applied to all years. Methodology v1.
- Approaches: FAA d-TPP metafile, current charting cycle; plates link to aeronav.faa.gov. No minimums are reproduced.
- Data freshness: METAR and D-ATIS refresh every minute on this page; the D-ATIS recorder ran 1 min ago; climatology through 2025-12-31.
